People who regularly stay up until the wee hours of the morning could be harming their mental health, a new study finds. Regardless of whether people were morning larks or a night owls, they tended to have higher rates of mental and behavioral disorders if they stayed up late, researchers found. The mental health risk associated with staying up late cropped up regardless of a person’s preferred sleep timing, also known as their chronotype. “We found that alignment with your chronotype is not crucial here, and that really it’s being up late that is not good for your mental health,” said senior researcher Jamie Zeitzer, a professor of psychiatry and behavioral sciences at Stanford Medicine, in California. “The big unknown is why.” These findings run counter to previous studies which found that people who stick to their chronotype tend to be healthier, Zeitzer added. For the study, researchers tracked nearly 74,000 middle-aged and older people in the United Kingdom. More than 19,000 said they were morning types, while about 6,800 identified as evening types. The rest fell somewhere in the middle. The participants were asked to wear an activity monitor to track their sleep over seven days. Their preferred sleep timing was then compared to both their actual sleep and their mental health, which was determined through their health records. Analysis showed that night owls…  read on >  read on >

Ambulances meant for people having a mental health crisis could help folks get the care they need with less confrontation and friction, a new study says. People transported to the hospital by a “psychiatric ambulance” required fewer restraints or coercive measures than those transported by the police, according to results from an Amsterdam program. In 2014, Amsterdam introduced a psychiatric ambulance service operated by a trained driver and a psychiatric nurse. It looks just the same as a typical ambulance, but inside it’s stripped of visible medical equipment to create a more tranquil environment. Patients can sit upright or lay on a stretcher, with a soft Velcro restraint or sedative medication available as needed. Researchers compared nearly 500 police transports in the four months prior to introduction of the psychiatric ambulance, and more than 650 ambulance transports that occurred within six months after the service started. They found stark differences when it came to the use of restraints: 86% of people transported by ambulance were not restrained, compared with 57% of those transported by police. 42% of people transported by police were handcuffed, compared to less than 1% who went by ambulance. However, the occurrence of aggressive events was similarly low in both the ambulance and police groups, around 2%. The rates of hospital admission were similar between the two groups, 36% for ambulance versus…  read on >  read on >

Caffeine has been associated with a reduced risk of developing Parkinson’s disease, but a new study says a coffee jolt might not be good for people already diagnosed with the brain disorder. Consuming caffeine appears to blunt the brain’s ability to use dopamine, the hormone that lies at the heart of Parkinson’s symptoms, researchers reported recently in the journal Annals of Neurology. Patients with high caffeine consumption had an 8% to 15% greater decrease in the ability of dopamine to bind with receptors in the brain, compared to those who took in less caffeine, results show.  “While caffeine may offer certain benefits in reducing risk of Parkinson’s disease, our study suggests that high caffeine intake has no benefit on the dopamine systems in already diagnosed patients,” said principal researcher Valtteri Kaasinen, a professor of neurology with the University of Turku in Finland. “A high caffeine intake did not result in reduced symptoms of the disease, such as improved motor function,” Kaasinen added in a university news release. Parkinson’s occurs when nerve cells that produce the brain chemical dopamine start to die.  Reduced levels of dopamine wind up causing the movement problems associated with the disease, including tremors, muscle stiffness and impaired balance and coordination. For this study, researchers performed brain scans on 163 early-stage Parkinson’s patients and 40 healthy people. The scans tracked changes in…  read on >  read on >

California skateboarder Jared Hager has become the first person to receive a transparent skull replacement, which allows doctors to better view the function of his brain. The window has allowed doctors to both monitor his progress and test new and better scanning methods for assessing brain health. Hager, 39, of Downey, Calif., sustained a traumatic brain injury from a skateboarding accident at a Palm Springs reservoir in April 2019. “I just went down this hill without even looking at it, which is like a really dumb thing to do,” Hager told ABC News. During emergency surgery, half of Hager’s skull was removed to relieve pressure on his brain. Doctors had planned to replace the skull bone once Hager recovered, but the pandemic derailed those plans. Elective surgeries were halted, leaving Hager with just skin and connective tissue protecting his brain for two years. “Even if a stick hits my head, it’s just my brain right here. It’s just my brain.” Hager recalled. But the timing made Hager a perfect candidate to receive an experimental skull implant made of a material that resembles plexiglass. Through this “window,” doctors have tested new ultrasound and CT techniques that produce high-resolution brain images. These brain imaging scans collect data on brain activity by measuring changes in blood flow or electrical impulses. They can provide key insights into how the…  read on >  read on >

America’s college students seem to be more stressed than ever, with a new report finding a sharp rise in cases of post-traumatic stress disorder (PTSD) and acute stress disorder (ASD) on campuses across the country. In a “national sample of U.S. college students, we found a notable increase in the prevalence of PTSD and ASD,” concluded a team led by Yusan Zhai, of the University of Alabama at Birmingham. Rates of PTSD rose by 4.1 percentage points between 2017 and 2022, and stress disorder diagnoses rose by 0.5 percentage points, the data showed. Their findings were published May 30 in the journal JAMA Network Open. As Zhai’s group explained, any number of events — campus shootings, sexual assault, physical violence and natural disasters, for example — can trigger either PTSD or ASD. PTSD can lead to more persistent symptoms, while ASD’s impact may be more transient — anywhere from a few days to a month. In their study, the Birmingham researchers focused on 2017 through 2022, “a period marked by escalated societal stressors and global health crises,” including, of course, the pandemic. They looked at data from the ongoing Healthy Minds study, which tracks the mental health of over 392,000 people attending 332 different colleges and universities across the United States. About 58% of the students were female. The data showed that during the study…  read on >  read on >

Even as suicide rates have risen among Americans generally, one group appears to be bucking that trend: People diagnosed with cancer. Experts are crediting improved access to counseling and other “psychosocial care” with easing the emotional toll of cancer and keeping more patients from making tragic decisions. Nevertheless, cancer patients still face elevated risks for suicide, noted a team led by Dr. Qiang Liu of the National Cancer Center at the Chinese Academy of Medical Sciences in Beijing. “The cancer-related suicide rate is estimated to be double that of the general population in the United States,” Liu’s group noted in the study. “Notably, the risk of suicide in men is significantly higher compared to women. This heightened cancer-related suicide risk remains elevated for up to 15 years following their diagnosis.” The new report was published May 27 in the journal Translational Psychiatry. In the study, Liu’s team looked at data on over 5 million Americans who’d been diagnosed with cancer between 1975 and 2017. Of the more than 8,000 who died by suicide, most (82%) were male, white (93%) and older (73% were ages 50 to 79). However, there was some good news: The rate at which suicide claimed the lives of people with cancer has declined steadily over the decades. These deaths first started to decline gradually between 1989 and 2013, the numbers showed,…  read on >  read on >

Stuttering is a neurological condition, not a psychological one, and scientists in Finland now believe they’ve found the disrupted network in the brain that may cause it. “These findings explain well-known features of stuttering, such as the motor difficulties in speech production and the significant variability in stuttering severity across emotional states,” said senior study author Juho Joutsa, a professor of neurology at the University of Turku. His team published its findings May 27 in the journal Brain. According to the researchers, anywhere from 5% to 10% of children will develop a stutter, and 1% of adults also struggle with stuttering. President Joe Biden has been open about his lifelong management of his own stuttering. “Stuttering was once considered a psychological disorder,” Jpoutsa said in a university news release. “However, with further research, it is now understood to be a brain disorder related to the regulation of speech production.” But just where in the brain a person’s stutter might originate has been unknown. In the study, Joutsa’s group first focused on 20 adults (ranging in age from 45 to 87) who all developed a stutter after suffering a stroke. Although the location in the brain where the stroke occurred varied between patients, the strokes did all seem to affect one particular brain network — unlike strokes that did not bring on stuttering. These networks connected…  read on >  read on >

The old joke holds that fatherhood causes a man’s hair to go prematurely gray. Whether or not that’s true, being a father does appear to put men at greater risk of poor heart health later in life, a new study finds. Dads tended to have worse heart health than men without kids, based on factors like diet, exercise, smoking, weight, blood pressure, cholesterol and blood sugar, researchers reported in the journal AJPM Focus. “The changes in heart health we found suggest that the added responsibility of childcare and the stress of transitioning to fatherhood may make it difficult for men to maintain a healthy lifestyle, such as a healthy diet and exercise,” said researcher Dr. John James Parker, an assistant professor of pediatrics and general internal medicine at Northwestern University Feinberg School of Medicine in Chicago. For the study, researchers analyzed data from more than 2,800 men ages 45 to 84. Although fathers had worse heart health, the study also found they actually have lower death rates than men without kids. That might be because fathers have a better social support system, and social connectedness has been linked to a lower risk of death, Parker said. “Fathers may also be more likely to have someone as their future caretaker [i.e., their children] to help them attend medical appointments and manage medications and treatments as they…  read on >  read on >

Folks typically think of heart disease as a byproduct of modern fast-food living, but a new study shows the condition has plagued humanity for centuries. More than a third (37%) of 237 adult mummies from seven different cultures spanning more than 4,000 years had evidence of clogged arteries, CT scans revealed. Researchers say the results show that humans have an innate risk of atherosclerosis — a build-up of plaque in the arteries that can lead to heart attack and stroke. “We found atherosclerosis in all time periods — dating before 2,500 BCE — in both men and women, in all seven cultures that were studied, and in both elites and non-elites,” said lead researcher Dr. Randall Thompson, a cardiologist at Saint Luke’s Mid America Heart Institute in Kansas City, Mo. “This further supports our previous observation that it is not just a modern condition caused by our modern lifestyles.” The mummies came from around the world, including ancient Egyptians, lowland ancient Peruvians, ancient highland Andean Bolivians, 19th century Aleutian Islander hunter-gatherers, 16th century Greenlandic Inuits, ancestral Puebloan, and Middle-Ages Gobi Desert pastoralists, researchers said. Most cases were consistent with early heart disease that’s often found on CT scans of modern patients, researchers said. The findings were published May 28 in the European Heart Journal. “This study indicates modern cardiovascular risk factors — such as smoking, sedentary…  read on >  read on >

A bilingual brain implant has allowed a stroke survivor to communicate in both Spanish and English, scientists report. Turning to an AI method known as a neural network, researchers trained the patient’s implant to decode words based on the brain activity produced when he tried to articulate those words, and then display those words and sentences on a screen. This method allows the brain implant to process data in a way that is similar to the human brain. Scientists at the University of California, San Francisco’s Center for Neural Engineering and Prostheses have labored for years to design a decoding system that could turn the patient’s brain activity into sentences in both languages. In a report published May 20 in the journal Nature Biomedical Engineering, the scientists share the details of their effort. “This new study is an important contribution for the emerging field of speech-restoration neuroprostheses,” Sergey Stavisky, a neuroscientist at the University of California, Davis, who was not involved in the study, said in a journal news release. Even though the study included only one patient and more research is needed, “there’s every reason to think that this strategy will work with higher accuracy in the future when combined with other recent advances,” Stavisky added. The saga of the bilingual brain implant first began five years ago. At age 20, a man identified…  read on >  read on >
